[PATCH] Convert a couple tests to unix text line endings.

[Pedro Alves <palves at redhat dot com>]

I noticed mi-reverse.exp had cr/lf line endings.  Looking a bit deeper, I
found one other file:

$ find . | xargs file | grep CRLF
./testsuite/gdb.mi/mi-reverse.exp:                           ASCII text, with CRLF line terminators
./testsuite/gdb.ada/packed_tagged/comp_bug.adb:              ASCII text, with CRLF line terminators

I've ran dos2unix on both files, and checked in the result.

2012-07-04  Pedro Alves  <palves@redhat.com>

	* gdb.ada/packed_tagged/comp_bug.adb: Convert to unix text line
	endings.
	* gdb.mi/mi-reverse.exp: Convert to unix text line endings.
